It won't cover many situations, I agree.

I would rather eat three correctly-sized meals a day than one very big
meal once a week.

Yes, and so what. My application has 7500 lines of PHP and 12000 or so
lines of javaScript. I see no prospect of being able to replace the
JavaScript by some clever CSS.

While some might, and with good reason, personally I don't take the
needs of search engines into account.

Mmm. In everything you say here, you make the mistake of assuming that
PHP, browser, JavaScript are components that can *only* be used in a
traditional browser-on-my-computer, server-somewhere-remote scenario.
This is an error.

Because reloading a page is messy and slow from the user's PoV. Instead
you can use AJAX to respond in a much more timely way depending what
they are doing. Or validate their form as they are entering it, or do
something like a postcode or address lookup. And yes, in most instances
you can offer a degraded approach in the case where the user *has*
turned off JS, but then they get a poorer service and may not understand
why.
